Experimental Remarks: The solubility of 1,3,5-cycloheptatriene in water at 25°C was reported to be 620 g(1)/106 g(2). The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.0620 g(1)/100 g sln and 1.21 x 10-4.

Experimental Data:(Notes on the Nomenclature)Method/Apparatus/Procedure: In a 250 mL glass bottle, 10-20 mL of (1) was vigorously shaken for 1 hr or magnetically stirred for 1 day, with 200 mL of (2) at 25 °C. The bottle was set aside for 2 days to allow droplets of undissolved (1) to separate. Absence of emulsion was checked microscopically. A sample of the hydrocarbon-saturated water was withdrawn with a Hamilton Syringe and gas liquid chromatograph in conjunction with a flame ionization detector.
